i.e instead of collecting privacy protecting, optional, accurate,
USEFUL, upgradable aggregate statistics, we will collect mandatory
ambiguous privacy violating statistically useless LOG FILES. Anything!
Just so we don't have to THINK. Or do something NEW.
This reminds me of nothing more than the current ipv6 link address
encoding lunacy. Another symptom of correlatory, rather than logical
thinking.

legs and a tail is a dog".

While the structure of P'->C' might be correlated to P->C. It isn't
P->C. It isn't P->C, because once you delve into the domain you
immediately find that P'2 associated only P'1 only indirectly. Via P'4
& P'3. Once you apply a little logic you realise that there is a
necessary AND between P'1 and P'2 that doesn't actually exist.
Kre's post was probably the worst example of this. Despite stating
that the feature would be made optional (opt out), Kre further spread
the taint to pkgsrc as a *whole*, refusing to use it at all. Nevermind
that whole chain of functional relevance could be disabled by the last
AND. (i.e AND the damned feature is TURNED ON AT ALL). I know this
happens sometimes to the best of us, but these sort of correlation
equals causation arguments are pure voodoo.
